Suppliers Bargaining Power
Commodity inputs
ESS Tech uses mostly industrial materials and standard manufacturing inputs, so it is not tied to the tight lithium, nickel, and cobalt chains that still drive battery shortages. Lithium carbonate prices have also fallen about 80% from the 2022 peak, which shows how fast commodity input costs can swing. That keeps supplier power moderate, but metal, chemical, and freight spikes can still squeeze margins.
Specialized components
ESS Tech, Inc. depends on specialized battery subsystems and power electronics, and only a small set of qualified vendors can meet grid-grade specs and reliability tests. That lifts supplier power because replacement options are narrow and qualification can take months. When a component is mission-critical, pricing and lead times tend to favor the supplier.
Contract manufacturing leverage
ESS Tech, Inc. relies on outside manufacturing partners for key fabrication steps, so those suppliers can shape unit cost, lead times, and shipped volume. When a contract manufacturer is tight on capacity, ESS Tech, Inc. faces higher switching costs and less room to negotiate. That keeps supplier power moderate, even if the core flow battery chemistry itself is not highly resource constrained.
Long lead times
Long lead times make ESS Tech, Inc. dependent on a few suppliers for cells, controls, enclosures, and power gear, so one late part can delay full system installs and push revenue recognition out. That leverage matters because battery projects are built as one chain, not as separate parts. If a supplier owns a bottleneck item, its pricing power rises fast.
- One late part can stop the whole project
- Bottleneck suppliers gain pricing leverage
- Delays hit cash flow and revenue timing
For ESS Tech, Inc., this raises supplier power even when demand is strong, because schedule risk can be worth more than small price cuts.
Equipment and tooling dependence
Scaling a battery factory depends on specialized automation, test systems, and plant machinery, so ESS Tech, Inc. faces supplier leverage when expansion picks up. When order books are tight, vendors can raise prices and stretch lead times, which lifts capex and slows ramp-up. For a young manufacturer, that makes equipment access a real bottleneck.
- Specialized tools, few qualified vendors
- Tight demand raises pricing power
- Expansion delays can hit cash flow
ESS Tech Supplier Leverage Stays Elevated Despite Cheaper Lithium
Supplier power for ESS Tech, Inc. is moderate to high because grid-grade power electronics, automation, and contract manufacturing come from a small vendor base, so one late part can slow full system installs. Lithium carbonate is down about 80% from its 2022 peak, which eases some commodity pressure, but specialized parts still set the pace. That keeps pricing and lead-time leverage with suppliers.
| Indicator | Latest data | What it means |
|---|---|---|
| Lithium carbonate | ~80% below 2022 peak | Lower raw-material pressure |
| Qualified supplier base | Small, specialized | Higher switching costs |

Customers Bargaining Power
Utility-scale buyers
ESS Tech, Inc. sells to utilities, developers, and large commercial buyers that often place multi-unit orders, so each deal can move the book. These buyers are sophisticated, use strong procurement teams, and can press hard on price, warranty terms, and delivery. With few large contracts on the table, their scale gives them real bargaining power.
Competitive bidding
Large ESS Tech, Inc. storage deals are often sold through RFPs, auctions, or negotiated tenders, so buyers can pit vendors against each other before award. That keeps customer power high because price, warranty length, and performance guarantees are all under review, not just upfront cost. In 2025, utility-scale storage buyers still had a wide menu of lithium-ion and non-lithium options, which makes switching and comparison easy.
High switching scrutiny
ESS Tech, Inc. faces high switching scrutiny because buyers compare lifecycle cost, safety, uptime, and financing risk before locking in a storage platform. If ESS Tech, Inc. cannot prove bankability or meet project specs, customers can delay awards or shift to rivals, which raises their leverage in price and contract talks. In utility storage, where projects often hinge on long-term performance guarantees and lender approval, that delay power is real.
Price sensitivity
ESS Tech, Inc. faces high customer bargaining power because battery storage buyers choose on economics, not chemistry alone. If another option delivers lower installed cost or better project IRR, buyers can switch fast, so price pressure stays high for ESS.
- Buyers compare total project returns.
- Lower cost alternatives win fast.
- Price pressure stays high for ESS.
Project financing influence
Project finance makes ESS Tech, Inc. buyers stronger because many deals hinge on lenders and insurers approving the battery system first. In utility storage, projects often run at 100+ MWh scale, so if financiers favor proven lithium-ion systems, customers can push for lower prices, stronger warranties, and tighter performance guarantees.
This is stronger than a normal product sale because the buyer’s real gatekeeper is the capital provider, not just the end user. One weak bankability view can stall the deal, so ESS Tech, Inc. may face tougher commercial terms even when demand for long-duration storage is high.
- Lenders can block unproven tech.
- Insurers may require extra terms.
- Buyers demand lower risk pricing.
- Commercial terms get tougher fast.
ESS Tech Faces Strong Buyer Leverage in Utility Battery Deals
Customer bargaining power for ESS Tech, Inc. is high because its buyers are utilities and developers that buy in large, bid-driven projects, often 100+ MWh. They compare price, warranty, uptime, and bankability, so even one tender can force tighter terms. If lenders favor proven battery systems, buyers can press ESS Tech, Inc. harder on price and guarantees.
| Buyer pressure factor | Why it matters |
|---|---|
| 100+ MWh projects | Large orders raise buyer leverage |
| RFP and tender sales | Easy vendor comparison |
| Lender approval | Can stall weakly bankable deals |

Rivalry Among Competitors
Lithium-ion dominance
Lithium-ion still sets the benchmark in stationary storage, with about 95% of new grid-scale battery storage deployments using that chemistry in 2025. That scale gives rivals cheaper packs, wider supplier access, and years of field data on performance. ESS Tech, Inc. has to win on safety, duration, and lifecycle cost to stand out against that installed base.
Long-duration storage competition
ESS Tech, Inc. faces intense rivalry in long-duration storage, where flow batteries, thermal systems, and other chemistries all chase the same utility and grid buyers. In 2025, LDES is moving from pilots to procurement, so vendors compete hard on cost, safety, cycle life, and bankability. That puts price pressure on ESS and makes win rates in utility RFPs a key battleground.
Utility proof points matter
Utility buyers usually award storage deals to vendors with the deepest field history, reference sites, and reliability data. In a market where rivals can point to many operating projects, trust builds faster than claims do. ESS Tech, Inc. has to show real uptime, cycle-life, and safety results in procurement to compete against better-known deployments.
Price and warranty pressure
Price and warranty pressure is high in ESS Tech, Inc. projects because buyers compare total installed cost, long warranty coverage, and degradation risk before signing. In utility storage, bids can swing by tens of dollars per kWh on installed cost, so rivals can cut price to win share and force ESS Tech, Inc. to defend margins.
This matters because flow battery buyers care about 10- to 20-year life claims, and any gap in warranty terms can shift deals fast. The result is heavier discounting across the industry and weaker gross profit for ESS Tech, Inc. if it must match lower bids.
- Total cost drives project wins
- Warranty terms shape buyer trust
- Degradation risk raises bid pressure
- Lower prices squeeze industry margins
Slow market expansion
Long-duration storage demand is rising, but not fast enough to ease rivalry. The market still centers on a limited set of utility-scale projects, so ESS Tech, Inc. competes with the same vendors for the same awards. In 2025, grid storage deal flow stayed concentrated in a few large procurements, keeping price pressure high.
- Few large utility contracts drive bids.
- Same projects attract many storage rivals.
ESS Tech Faces Fierce Competition in a Li-ion-Dominated Market
Competitive rivalry is high for ESS Tech, Inc. because utility buyers can compare many long-duration storage options on one bid. In 2025, lithium-ion still held about 95% of new grid-scale battery deployments, so ESS Tech, Inc. fights an entrenched, lower-cost benchmark. Flow batteries, thermal storage, and other LDES rivals also push hard on price, warranty, and bankability.
| Metric | 2025 level |
|---|---|
| Li-ion share of new grid storage | About 95% |
| Key rivalry factors | Price, safety, life, bankability |
| Buyer behavior | Few large utility procurements |
Substitutes Threaten
Lithium-ion batteries
Lithium-ion batteries are ESS Tech, Inc.'s most direct substitute in many storage jobs, especially 2 to 4 hour systems. The pressure is high because lithium-ion still dominates the grid storage market, with LFP pack costs near $115 per kWh in 2024 and broad developer familiarity. For shorter-duration projects, that cost and availability edge often beats ESS Tech, Inc.'s longer-life iron flow pitch.
Pumped hydro storage
Pumped hydro is a real threat because it can deliver grid-scale, long-duration storage where geography fits. The IEA said global pumped storage capacity was about 180 GW in 2024, far above most battery fleets, but projects take years and heavy capex. In markets with available sites, it can beat battery projects on duration and displace ESS Tech, Inc. on grid balancing bids.
Demand response programs
Demand response is a real substitute for ESS Tech, Inc. in some behind-the-meter uses because it cuts peak load without a battery. U.S. demand response resources were about 29 GW in FERC’s latest national count, showing scale. That makes the threat meaningful where customers can shift loads cheaply, especially if battery payback is weak.
Hydrogen and thermal storage
Hydrogen and thermal storage can cover long-duration use cases that iron flow batteries do not always win, especially multi-day backup. That threat is still early, but it is real: the IEA says global clean hydrogen investment stayed above $1 billion per day in 2024, and thermal storage projects are scaling in grid and industrial heat markets.
- Best fit: long-duration demand
- Hydrogen is still less mature
- Thermal storage is gaining capital
- Share risk rises in niche markets
Grid upgrades and peakers
Utilities can still fix reliability with grid upgrades and peaker plants, so ESS Tech, Inc. is not the only answer. The U.S. had about 26 GW of utility-scale battery storage online by end-2024, but gas peakers and transmission spend can still delay some storage deals. So substitution pressure stays real, even if these assets are not direct one-for-one replacements.
- Peakers cut near-term storage need.
- Grid upgrades can defer ESS Tech, Inc. projects.
- Storage still wins on speed and flexibility.
ESS Tech Faces Fierce Substitute Pressure in Long-Duration Storage
Substitution pressure on ESS Tech, Inc. is high because lithium-ion still wins most 2–4 hour jobs, with LFP pack costs near $115/kWh in 2024. Pumped hydro, demand response, hydrogen, and thermal storage also cover parts of the same need, so ESS Tech, Inc. must win on long life, safety, and multi-day storage.
| Substitute | Key data |
|---|---|
| Li-ion | $115/kWh |
| Pumped hydro | 180 GW |
| Demand response | 29 GW |
Entrants Threaten
Capital intensity
Battery manufacturing is capital heavy: plants, test lines, and inventory must be funded before scale. In 2025, ESS Tech still faced a market where utility-scale battery factories can need hundreds of millions of dollars in upfront buildout, so new entrants must lock in large capital before they sell much. That cash burden, plus working capital, makes entry hard and slows rivals.
Bankability hurdle
Utility buyers want bankable suppliers: long operating histories, 20-year-style warranties, and field data that prove uptime over thousands of cycles. New entrants without that proof usually struggle to win large utility contracts, even if the chemistry works in the lab.
That makes the entry bar high for ESS Tech, Inc. because the customer is not just buying a battery, but 10-plus years of reliability and service support. Without that track record, lenders and utilities often delay orders or demand tougher terms.
So the chemistry can be good, but bankability decides who gets the deal.
Engineering know-how
Flow battery design, system integration, and controls need niche engineering skill, so new entrants face a steep learning curve. ESS Tech, Inc. still operates in a capital-heavy market where safe, durable grid systems are hard to build and validate, which raises technical and launch risk. That slows entry and helps protect incumbents with proven field performance.
Certification and permitting
Energy storage systems must clear UL 9540, UL 9540A, NFPA 855, utility codes, and local AHJ permits, so certification can take months and expose design flaws. For ESS Tech, Inc., that slows scale-up and raises fixed costs before one unit ships.
These hurdles hit small entrants hardest: test programs, third-party reviews, and permit work can run into six figures per project, while major fires have made regulators stricter on battery siting and setbacks.
- Long certification cycles delay revenue.
- Safety tests can force redesigns.
- Compliance costs block underfunded rivals.
Lower barriers from modular design
Modular battery design lowers the cost and time to enter ESS Tech, Inc.'s market because startups can buy parts, outsource assembly, and target narrow use cases. That does not erase the engineering and safety hurdles, but it does mean new players do not need a full in-house factory to start. So the threat of new entrants stays moderate, not low.
- Outsourced production cuts upfront capex.
- Niche offerings can reach market faster.
- Modularity weakens scale barriers.
ESS Tech: High Bar Keeps New Battery Storage Entrants at Bay
Threat of new entrants is moderate for ESS Tech, Inc. Utility-scale storage needs huge upfront capital, long safety testing, and bankable field history, so most startups stall before first large orders. In 2025, buyers still wanted long warranties and proven uptime, which raised the bar. Modular design lowers entry cost, but not enough to erase certification and trust hurdles.
| Barrier | 2025 impact |
|---|---|
| Factory capex | Hundreds of millions |
| Certifications | Months of testing |
| Buyer trust | Long warranty demand |
